We report here the catalytic isomerization of aryl-substituted allylic alcohols mediated by lanthanide alkoxide complexes. The conversion yields allylcarbinols as the products of the olefin isomerization process, but with different olefinic positions than those afforded by typical transition metal catalysts. The average isolated product yields in these reactions are 65-81%. The catalytic cycle and the source of the unusual olefinic positioning are proposed to involve a strong interaction between the Lewis acidic La 3+ ion and the substrate hydroxyl group.
